Three people are dead after excessive rainfall inundated southeastern Queensland on Friday, causing Brisbane to shatter its May daily rainfall record.
The three fatalities occurred when the car they were riding in washed off a flooded road in Caboolture, which is located north of Brisbane, reported the Australian Broadcasting Corporation (ABC News).
An eight-year-old boy was among the dead.
Data obtained by Australia's Bureau of Meteorology indicates that one weather reporting station in Caboolture received 333 mm (13.11 inches) of rain from Friday morning (at 9 a.m. local time) to Friday evening.
The nearby town of Beerburrum was inundated with 233 mm (9.17 inches) on Friday from 9 a.m. to 10 p.m. local time. Out of that total, 148.6 mm (5.85 inches) fell in just three hours.
Queensland's capital of Brisbane recorded 182.6 mm (7.19 inches) on Friday from 9 a.m. to 11:30 p.m. That was preceded by 56.2 mm (2.21 inches) the previous 24 hours.
Friday is now the wettest May day on record at the Brisbane Regional Office. The previous record was 149 mm (5.87 inches) from May 9, 1980. Brisbane averages nearly 74 mm (2.90 inches) during the entire month of May.

ABC News reports that officials performed 19 swift-water rescues in Brisbane alone on Friday. The Caboolture Hospital was cut off, causing emergency crews to divert new patients to nearby hospitals.
Tropical Cyclone Quang was not the culprit behind Friday's excessive rainfall. Quang slammed into Western Australia as a weakening tropical cyclone but still kicked up a 120 kph (75 mph) wind gust at Learmonth, according to AccuWeather.com Senior Meteorologist Jason Nicholls. West Cape recorded 52 mm (2.05 inches) of rainfall.
Instead, the excessive rainfall in Queensland was the result of a non-tropical storm system that slowly dropped southward through the area and tapped into deep moisture.
Rainfall has shifted out of Queensland and into eastern New South Wales, but is no longer falling excessively heavy. Around 12 mm (0.50 of an inch) is expected in Sydney on Saturday.
Southeastern Queensland will welcome a much-needed dry weekend aside from a stray shower grazing the Gold Coast on Sunday. While the rain has come to an end, residents should remain on alert for dangerously high rivers as runoff from the rain drains downstream.
